@isuruf I think cmake is passing the fortran files -DLINUX and such. I tried to kill that but failed. Do you have any ideas there?

Also, heres, _fortio_binary_mode:

int
__io_binary_mode(void *fp)
{
#if defined(WINNT)
#include <fcntl.h>

#if defined(WIN64) || defined(WIN32)
#define O_BINARY _O_BINARY
#endif

 int mode;

 mode = setmode(fileno((FILE *)fp), O_BINARY);
 if (mode == -1) {
   /* The mode argument is clearly legal, so this should not
    * happen.  But, in a console app, setmode will fail on
    * the fd representing stdout.
    */
   return 0;
 }
 (void)setmode(fileno((FILE *)fp), mode);
 return (mode & O_BINARY);
#else
 return 1;
#endif
}

It's done here, https://github.com/flang-compiler/clang/blob/flang_release_40/lib/Driver/Tools.cpp#L4702

That's not what I'm talking about. This is nmake output:

This requires advapi32.lib, see https://msdn.microsoft.com/en-us/library/ms724432(VS.85).aspx#Mtps_DropDownFilterText

@isuruf this approach is completely wrong, should be

void printStack( void )
{
     unsigned int   i;
     void         * stack[ 100 ];
     unsigned short frames;
     SYMBOL_INFO  * symbol;
     HANDLE         process;

     process = GetCurrentProcess();

     SymInitialize( process, NULL, TRUE );

     frames               = CaptureStackBackTrace( 0, 100, stack, NULL );
     symbol               = ( SYMBOL_INFO * )calloc( sizeof( SYMBOL_INFO ) + 256 * sizeof( char ), 1 );
     symbol->MaxNameLen   = 255;
     symbol->SizeOfStruct = sizeof( SYMBOL_INFO );

     for( i = 0; i < frames; i++ )
     {
         SymFromAddr( process, ( DWORD64 )( stack[ i ] ), 0, symbol );

         printf( "%i: %s - 0x%0X\n", frames - i - 1, symbol->Name, symbol->Address );
     }

     free( symbol );
}
